Merge branch 'add-noinline_for_tracing-and-apply-it-to-tcp_drop_reason'
Yafang Shao says:
====================
Add noinline_for_tracing and apply it to tcp_drop_reason
This patchset introduces a new compiler annotation, noinline_for_tracing,
designed to prevent specific functions from being inlined to facilitate
tracing. In Patch #2, this annotation is applied to the tcp_drop_reason().
